I give this product an overall score of 4. (I purchased this several months ago and installed right after my granite counter tops went in back in early February 2014.)  It is a beautiful faucet and, next to the granite counter tops, is the first thing my guests comment on when they see my updated kitchen. Easy to install, and I love the way it works with the touch button change between spray and regular flow. Makes cleaning dishes a little more enjoyable. 

My only complaint is that it doesn't stay where I put it. It likes to swing to the right and the center. When I swing it left (the deep side of my sink), it swings itself right again. We've messed with the weight and all of that, but it hasn't helped.  A nuisance. But, still, for the overall value and beauty of the faucet, I don't mind much.
